description: First-run check: toolchain, test command, model tiers, and conflicts with other plugins.
argument-hint: ""

Check and report, changing nothing without a yes:

• the project language and test command (`superlite-cli testcmd`, `test-cmd.json` or detection) and that it runs;
• Python 3.10+ for the `superlite-cli` tools;
• the model tiers in `config/models.json` and `config/routing.json`;
• whether a superlite run has superpowers suspended (`.superlite/peers.json`); it stays suspended until `superlite-cli finish`, then superpowers can be used again;
• whether `.superlite/` is gitignored.

Give a pass or fix line for each.
